Abstract: GAS-FIRED HEATERS WITH BURNERS WHICH OPERATE WITHOUT SECONDARY AIR A gas-fired burner apparatus (2) includes a porous combustion surface (5) disposed in a combustion chamber (8) substantially sealed to prevent entry of secondary combustion air. A subatmospheric pressure is maintained in the combustion chamber (8) by a natural or aspirated draft. The subatmospheric pressure cooperates with an aspirating flow of fuel to the burner apparatus (2) to provide an increased flow of primary combustion air which reduces the combustion temperature and the emission of pollutants. Alternatively, the subatmospheric pressure may be used to achieve a given flow of primary combustion air with a reduced combustion surface area. In both cases the risk of igniting inflammable vapour that may be present around the heater is eliminated by preventing secondary air from contacting the flame front. Water heater (1) and room heater applications of the burner apparatus are illustrated.

Abstract: Abstract A plastic tamper-indicating closure (1) possesses a closure cap (2) on which, by means of weakened web portions (5), a tamper-indicating band (6) is fixed. The tamper-indicating band (6) is provided with a number of blocking elements (8). The blocking elements (8) are connected with the tamper-indicating band via integral hinges (7). During screwing onto the container neck, the blocking elements (8) can be pivoted upwards and radially outwards into a first closed position (I). As opposed to this, during opening of the tamper-indicating closure the blocking elements are pivoted downwards and radially inwards into a second opening position (II). With that, the effective internal diameter will be reduced, by which means the blocking element will be held in engagement with the corresponding locking surface on a container neck.

Abstract: CARTRIDGE MAGAZINE HAVING A METAL BODY      USED WITH A PLASTIC FIREARM                             ABSTRACT    A magazine is disclosed for use with a pistol having a plastic firearm latch that is used to hold the magazine in the pistol well.   The magazine includes an all metal magazine body.   A non-metal  magazine  latch member  is connected to the magazine body.  When the magazine is held in the pistol well, the plastic firearm latch in the pistol engages the  non-metal magazine  latch member.    In  one embodiment,  a  carbon  fiber  filled  firearm  latch  is substituted  for the plastic  firearm  latch. A  spacer assembly is held adjacent an end wall of the magazine body.          The  spacer  assembly  has  a  smooth  outer  surface  for engagement by rim ends of cartridges during their movement relative to the magazine body.   A non-symmetrical  rib formed on the inner surface of a side wall of the magazine body is engagable by cartridges during their movement to prevent a premature bolt hold open condition.  The magazine includes a follower assembly in which the crown section is located adjacent a side wall of the follower body opposite the side wall that is adjacent to the bolt hold open latch.          This arrangement assists in providing the proper engagement between the bolt hold open latch and a bolt hold open mechanism in the pistol.

Title: Neem component as a male contraceptive
Inventor: TALWAR GURSARAN P
IPC: A61F6/20
Filed: 1994-07-22
Abstract: ABSTRACT         An alternate approach to vasectomy for long term male contraception following a single intra-vas application of a traditional plant (Azadirachta indica) product having immuno-modulatory properties is described.  The intra-vas administration of neem oil to male rate resulted in a block of spermatogenesis without affecting the testosterone production, the seminiferous tubules, although reduced in diameter, appeared normal and contained mostly early spermatogenic cells.  No antisperm antibody could be detected in the serum.  Unilateral administration of neem oil in the vas resulted in a significant reduction of testicular size and spermatogenic block only on the side of application, the draining lymph node cells of the treated side also showed enhanced proliferative response to in vitro mitogen challenge.  These results indicate that intra-vas application of neem oil is effective in blocking fertility in male mammals after a single injection.

Title: Scalable tree structured high speed i/o subsystem architecture
Inventor: MILLER CRAIG A
IPC: G06F13/40
Filed: 1993-12-06
Abstract: SCALABLE TREE STRUCTURED HIGH SPEED I/O SUBSYSTEM ARCHITECTURE       ABSTRACT      A point to point connection architecture for a computer I/O subsystem,  resulting in a scalable tree structure.   A Master I/O Concentrator (MIOC) is connected to the host bus and handles conversion between a bus oriented structure and the tree structure of the I/O subsystem.  Ports away from the host bus are downstream ports and conform to a simple byte wide message protocol.  Various IOCs and devices can be attached to one of the downstream ports on the MIOC.   The MIOC directs transmissions  to  the  appropriate  channel  based  on  a geographical addressing scheme.   The IOC connections act as further points of branching.  Ultimately IOD or I/O devices are reached, having an upstream port for connection to the IOC and a downstream port and internal  logic appropriate  for the particular peripheral device.  Various registers are present in the IOCs and the IODs to allow determination of the topology and particular devices present. Messages and commands are transferred in the I/O subsystem in defined packets. Various read,  write  and  exchange  commands  are used,  with  a  read response  being  utilized  to  allow  split  transaction  read operations.   Certain status and  control commands  are also present.  Interrupts are handled by having the interrupt levels correspond to memory addresses of the programmable interrupt controller, thus allowing simple selection of interrupts to be generated by the devices and no need for separate wiring.

IPC: B21K1/74
Filed: 1994-08-23
Abstract: A frame supports an interchangeable mandrel or die which receives the center portion of an elongated metal rod having opposite threaded end portions, and the rod is clamped to the die by a locking bar actuated by a hydraulic cylinder. The frame also includes a set of vertically spaced cross members connected by a pair of parallel spaced guide rods which support a carrier bar for vertical movement. The carrier bar pivotally supports corresponding end portions of a pair of arms each formed by parallel spaced plates, and each pair of plates defines slightly angled aligned cam slots. A pair of bending rollers are supported by the opposite end portions of the arms, and a hub member extends between the plates of each arm and supports rollers which engage the corresponding cam slots to provide for moving the arms and bending rollers along non-parallel converging paths for overbending the rod around the die. An elongated adjustment screw is rotatably supported by the lower cross member and extends between the plates forming the arms. The screw has oppositely threaded portions engaging the hub members to provide for conveniently and precisely adjusting the spacing between the bending rollers for accommodating dies and rods of different sizes.

Title: Method for data compression having an improved encoding algorithm which utilizes a token stacking technique
Inventor: GRAYBILL MARK D
IPC: G06T9/00
Filed: 1992-12-23
Abstract: 2131823 9322842 PCTABScor01 The present invention is a data compression method having an improved encoding algorithm which utilizes a token stacking technique. The essential step of the present invention encoding method is constructing a group of stacked tokens. Each stacked token has multiple fields including a substring length counter field and a backward displacement pointer field, where the former is identical among all stacked tokens for serving as the basis in constructing the group of stacked tokens, and the latter is assigned with a respective range of integers. The ranges assigned to the stacked tokens are stacked sequentially without overlapping. The encoding method further comprises the steps of determining a backward displacement pointer for a compressible substring and encoding the backward displacement pointer into a respective stacked token according to the range assigned, such that the backward displacement pointer falls within the range assigned to the respective stacked token. The present invention encoding method is particularly effective in saving the number of bytes required for encoding compressible substrings which are remotely located from their respective previously processed identical substrings because the larger backward displacement pointer can be encoded in a stacked token assigned with a stacked and shifted range of backward displacement pointers.
